> Would you elaborate on your last two sentences? Especially the latter one; which lossless format?
Sure. In the first sentence I was trying to say that if you use File | Render As… and look under the Save as type you will see MainConcept AVC/AAC (*.mp4) and Sony AVC (*.mp4;*.m2ts;*.avc) as types that you can render two. Both of these use the MPEG-4/h.264 codec. This will not be Quicktime format but it will be h.264.
In the second sentence, by lossless format I am refering to codecs that simply compress but don’t throw any information away. Rendering Uncompressed will, of course, be lossless. Also the Quicktime Animation codec is lossless, as is Huffyuv and Lagarith but these two do not ship with Vegas and you would have to download and install them.
So one solution might be to render as Quicktime Animation out of Vegas and then drop that into Quicktime Pro and render as h.264. This workflow will preserve the full quality coming out of Vegas and give you the h.264 file you want with Quicktime Pro.
